As The Next Web reports, Samsung is finally bringing to market (in Russia, to start) a phone, the Samzung Z, running the Tizen OS. Like Android, Tizen is based on the Linux kernel, but it's intended for HTML5 apps rather than Android apps. It's not Samsung's first Tizen device, though; the second-generation of its Gear smart-watches are running Tizen as well. "Samsung earlier revealed plans for its first Tizen smartphones to be launched during its second quarter of business in 2014, which runs April to July, so it seems like smartphones other than Samsung Z could still be on their way. The Samsung executive said that Tizen devices could account for as much as 15 percent of Samsung’s mobile shipments per year, but Android will still be its main business."
